Hi, I have some problem, which puzzles me a little bit with pjsua2 under Android. I successfully can start a call but it seems like I am unsuccessful in completely stopping it. The audio (OpenSL ES) is still running after calling pj::Call::hangup( pj::CallOpParam() ); I suppose I do need to do some further clean-up-work either before or after calling hangup? Is this correct? Maybe stopping/disconnecting the media in the onCallMediaState-handler similarly to it's start there? Would be nice if someone could push me towards the things to take a deeper look into in such a case like this. many thanks, Stefan
